Final answer:
Primary reinforcers are innate reinforcers that satisfy basic needs and provide pleasure, while secondary reinforcers have no intrinsic value and only have reinforcing qualities when linked with primary reinforcers.
Step-by-step explanation:
Primary reinforcers are innate reinforcers that have inherent reinforcing qualities, such as food, water, sleep, shelter, and pleasure. They satisfy basic needs and provide intrinsic pleasure. On the other hand, secondary reinforcers have no intrinsic value and only have reinforcing qualities when linked with primary reinforcers. Examples of secondary reinforcers include praise, money, stickers, and other things that can be used to obtain primary reinforcers or other secondary reinforcers.
